3 Claims.

1 This invention relates to sash fasteners particularly adapted for combination storm and screen doors which provide a frame for permanent mounting, and interchangeable glass storm sash section, and screen section or panels, for

use respectively in winter and summer. The invention is, however, adapted as well to the securing in place in a door, of any removable sash panel.

One of the objects of the invention is the provision of a fastener characterized by flatness of form, simplicity in construction, efiiciency in operation and cheapness to manufacture.

Another object of the invention is the provision of a fastener which wiH permit the removal or replacement of the sash panel by a simple finger movement of the fastener, and without the use of any tools whatsoever.

Still another object of the invention is to provide a fastener adapted to be mounted in a slot in the side of the sash panel, substantially in the plane of the inner face of the glass or screen, having a handle portion extending within operating access beyond the frame, enclosing the screen orglass, and having a latch portion retracted when the handle is raised by protruding beyond the frame and into a recess on the adjacent side of the door when the handle is moved to latched position.

A further object of the invention is so to shape the handle portion of the fastener that it lies flush with the inside face of the frame of the sash panel when in latched position, forming a closure of the slot through which it extends, keeping spiders, moths and other insects from entering said slot to build webs and cocoons.

Another object of the invention is the provision of a bevelled side to the recess in the door frame against which the latch portion of the fastener cams, drawing the sash panel into tight relation to the door frame, making the construction draftand rattle-proof.

Other objects of the invention will appear as the following description of a preferred and practical embodiment thereof proceeds;

In the drawing which accompanies and forms a part of the following specification, and throughout the several figures of which the same characters of reference have been employed to denote identical parts:

Figure 1 is a front elevation of a combination door with the glasspanel in place, embodying the features of the present invention;

Figure 2 is a front elevation showing the screen section;

Figure 3 is a perspective view of the fastener;

Figure 4 is a vertical section through a portion of the door and the adjacent side of the sash panel showing the fastener in latched position;

Figure 5 is a section taken along the line 5-5 of Figure 4; v

Figure 6 is a side elevation of a fragment of the door and sash panel showing in phantom the slots in which the fastener plays, the fastener being shown in unlatched position; and

Figure '7 is a cross section taken along the line 7-7 of Figure 4.

Referring now in detail to the several figures, the combination door 1 is constructed in the customary manner with the stiles 2 and 3 and top and bottom rails 4 and 5, respectively. The mid dle rail 6 may be positioned at any desired height, but is here shown relatively low so as to define with the stiles and top rail a rectangular. opening 7, Figure 7, for the reception of the removable panel. The sides of the stiles and the top and middle frame adjacent the opening are rabbeted so as to form a peripheral integral bead 3, Figure '7, preferably on the outside of the door and against which the removable panel rests when in place.

As a rule, the combination door is furnished with two panels, each comprising a frame, the side members of which are indicated by the reference characters 9 and 10. One panel is glazed for use in winter, while the other is covered with an insect-excluding screen. The glazed panel is shown in position in the door in Figure 1, while the screen panel is shown in Figure 2.

The fastening device comprising a flat member 11 having divergent arms 12 and 13, the former of which constitutes the latch element, while the latter functions as a handle for manipulating the fastener. At an intermediate point, the fastener is formed with a hole 14, the frame member 9 of the panel is formed with a flat slot 15 preferably opening adjacent the plane of the inner side of the glass or screen as shown in Figure 7. The slot is conveniently made with a circular saw, which accounts for its shape as shown in Figure 4. The shape of the slot 15, is made as shown to stop movement of the fastening device 13.

The fastener is introduced into the slot and a screw, rivet or other pivoting element 16 is passed through the wood on both sides of the slot and through the hole 14, securing the fastening element in place. The handle portion 13 is preferably rectilinear for a considerable portion of its length as shown at 1'7 in Figure 4, and the pivot is so located with respect to the slot that when the handle portion is in the latched position shown in Fig. 4, the rectilinear side thereof preferably'coincides with the inner edge of the side frame member, and the opening of the slot through which the handle portion projects is so positioned and dimensioned that when the fastener is in the latched position as shown, the handle member substantially closes the entrance to the slot, thereby excluding spiders, caterpillars, or other web or cocoon making insects. The latch portion 12 projects into a shallow slot 18 formed in the adjacent stile of the door, said slot having a sloping wall 19 upon which the latch portion cams, drawing the sash into tight relation to the bead 8, thereby avoiding rattling or drafts.

The fastener being flat, the projecting end of the handle portion 13 lies substantially against the glass or screen so that it is incapable of catching on clothing. Nevertheless, it is readily manipulated by a slight push of the finger in one or the other direction. In View of the altogether flat nature of the fastener, there is no part thereof projecting beyond the depth dimension of the door frame, so that doors equipped with my improved fastener my be piled flat for purpose of shipping, or for sale.

Any desired number of fasteners may beused for a single panel, depending mainly upon its length. In the drawing two fasteners 11 are shown, one near the top and the other near the bottom, along one side only. On the other side, pronged lugs 20 are driven into the door stile and the lugs left protruding about one-fourth inch. The projecting portions of the lugs 20 are adapted to fit into saw slots in the sash and screen panel stiles. The panel is then pushed into place, first engaging the lugs and when flat against bead 8, the handle portions of the fasteners are pressed downwardly to the position shown in Figure 4, forcing the panel snugly into place, by reason of the cam action of the fastener 12 against the beveled slot 18.

While I have in the above description disclosed what I believe to be a preferred and practical embodiment of my invention, it is to be understood that the specific shape of the fastener is a matter of choice except insofar as its shape must be such as to enable it to perform the functions herein attributed to the invention.

What I claim is:

1. In combination, a frame, a member of a removable panel adjacent said frame, the latter having a slot extending therethrough, one side of said slot being in juxta-position to a shallow slot opening in the adjacent side of said frame, a fastener pivotally mounted in the slot, in said panel member, having a latch portion extensible into said shallow slot, and a handle portion on the opposite side of said panel member, said handle substantially closing the end of the slot through which it protrudes when the fastener is in latched position.

2. In combination, a frame, a member of a removable panel adjacent said frame, the latter having a slot extending therethrough the outer end of said slot being in juxta-position to a shallow slot opening in the adjacent side of said frame, a flat fastener pivotally mounted in the slot in said frame having a latch portion extensible into the shallow slot in said frame, and a handle portion extending through the opposite side of the slot in said frame, said handle portion closing the end of the slot through which it extends, when the fastener is in latched position.

3. In combination, a frame, a member of a removable panel adjacent said frame, said frame having an opening with a surrounding head on one side and said panel member being adapted to fit said opening and seat against said bead, a side of the panel member having a flat slot extending therethrough in juxta-position to a shallow slot opening in the adjacent frame, a flat fastener pivotally mounted in the slot in said frame having a latch portion extensible into said shallow slot, and having a handle portion extending through the opposite end of the slot in said frame and closing the said end of said slot in said frame when in latched position, the shallow slot having a beveled wall against which the latch portion of said fastener cams for drawing said panel into tight engagement with said bead.
